Fitting adapted for holding an upright coupling member disposed in a motor
casing onto a flat ceiling wall
Abstract
A fitting includes a mounting bracket to be fixed on a ceiling wall, and
with two side edge portions opposite to each other to define an uppermost
abutment plane. Two mounting walls extend downwards from the side edge
portions, and have positioning walls axially spaced apart from the plane.
An anchoring seat is disposed on one of the mounting walls immediately
upstream of the positioning wall in a clockwise or counterclockwise
direction, and is spaced apart from the plane with a width larger than
that between the positioning wall and the plane. A protective covering
member includes an upper annular secured portion, an anchored portion
extending from the secured portion radially, inwardly and downwardly so as
to engage the anchoring seat for suspending the covering member from the
mounting bracket in a non-fastened state, and a supported portion
extending from the secured portion radially and inwardly. When the secured
portion is brought towards the plane from the non-fastened state, a
subsequent adjustment of the position of the upper annular secured portion
will shift the anchored portion to the positioning wall, thereby bringing
the supported portion to sit on the other positioning wall so as to place
the covering member in a ready state for fastening. In this state,
fastening members can tighten the secured portion on the mounting walls.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to ceiling fans. More particularly, this invention
relates to a fitting adapted for holding an upright coupling member
disposed in an upper wall of a motor casing onto a flat ceiling wall.
2. Description of the Background Art
Referring to FIG. 1, a conventional ceiling fan 10 is shown to include a
mounting bracket 11 which has an upper major wall for mounting on a
ceiling wall, and lateral mounting walls with screw holes 111. A
protective canopy covering member 12 has an upper annular secured portion
with through holes 121 such that screw fasteners 122 can pass through the
through holes 121 and engage threadedly the screw holes 111 to tighten the
protective covering member in the form of a canopy 12 on the mounting
bracket 11. A motor casing 13 has a motor therein, and an upper wall which
is disposed with a coupling member 131 that is secured on the protective
covering member 12.
During assembly, since the protective covering member 12 is connected with
the motor casing 13 before being secured on the mounting bracket 11 by the
screw fasteners 122, the user needs to hold the protective covering member
12 using one hand to align the through holes 121 and the screw holes 111,
and to position the screw fasteners 122 and to rotate the same using the
other hand. The assembly as such is relatively inconvenient to conduct.
More recent improvements have comprised J-shaped holes 121 that allow the
weight of the canopy member 12 to be hung onto the screws 122 while the
screws are then tightened.
Therefore, it is an object of this invention to provide an improvement
which overcomes the aforementioned inadequacies of the prior art devices
and provides an improvement which is a significant contribution to the
advancement of the ceiling fan art.
Another object of this invention is to provide a fitting which facilitates
assembly of a protective covering member in the form of a canopy to a
mounting bracket of a ceiling fan.
The foregoing has outlined some of the pertinent objects of the invention.
These objects should be construed to be merely illustrative of some of the
more prominent features and applications of the intended invention. Many
other beneficial results can be attained by applying the disclosed
invention in a different manner or modifying the invention within the
scope of the disclosure. Accordingly, other objects and a fuller
understanding of the invention may be had by referring to the summary of
the invention and the detailed description of the preferred embodiment in
addition to the scope of the invention defined by the claims taken in
conjunction with the accompanying drawings.
SUMMARY OF THE INVENTION
For the purpose of summarizing this invention, this invention comprises a
fitting which includes a mounting bracket and a protective covering member
in the form of a canopy. The mounting bracket includes an upper major wall
which is adapted to be fixed on and to abut against a ceiling wall, and
which has two side edge portions opposite to each other to define an
uppermost abutment plane in a radial direction relative to a first axis of
an upright coupling member of a ceiling fan. Rightmost and leftmost
mounting walls respectively extend downwards from the two side edge
portions, and have positioning walls spaced apart from the uppermost
abutment plane in an axial direction parallel to the first axis. The
positioning walls extend parallel to the uppermost abutment plane and
about the first axis so as to be angularly spaced from each other. In
addition, one of the rightmost and leftmost mounting walls includes an
anchoring seat which is disposed immediately upstream of the corresponding
positioning wall in a clockwise or counterclockwise direction, and which
is disposed to be spaced apart from the uppermost abutment plane with a
width in the first axial direction that is larger than a width between the
positioning wall and the uppermost abutment plane. A pair of arms are
disposed to be spaced apart from each other in the radial direction for
receiving and holding the upright coupling member.
The protective covering member in the form of a canopy includes an upper
annular secured portion with an uppermost peripheral edge, a skirt portion
which circumferentially extends from the annular secured portion about a
second axis and downwardly for insertion of the upright coupling member,
an anchored portion in the form of a hook which extends from the uppermost
peripheral edge radially, inwardly and downwardly such that when the
anchored portion is brought to engage the anchoring seat, the protective
covering member will be suspended from the mounting bracket in a
non-fastened state, and a supported portion in the form of a tab which
extends from the uppermost peripheral edge radially and inwardly, and
which is spaced from the anchored portion angularly. As such, when the
uppermost peripheral edge is brought towards the uppermost abutment plane
from the non-fastened state so as to bring the second axis to coincide
with the first axis, a subsequent adjustment of the position of the upper
annular secured portion relative to the rightmost and leftmost mounting
walls in the clockwise or counterclockwise direction will shift the
anchored portion to the corresponding positioning wall, thereby bringing
the supported portion to sit on the other positioning wall so as to place
the protective covering member in a ready state for fastening. In this
state, a pair of fastening members can be disposed to tighten the upper
annular secured portion on the rightmost and leftmost mounting walls.
The foregoing has outlined rather broadly the more pertinent and important
features of the present invention in order that the detailed description
of the invention that follows may be better understood so that the present
contribution to the art can be more fully appreciated. Additional features
of the invention will be described hereinafter which form the subject of
the claims of the invention. It should be appreciated by those skilled in
the art that the conception and the specific embodiment disclosed may be
readily utilized as a basis for modifying or designing other structures
for carrying out the same purposes of the present invention. It should
also be realized by those skilled in the art that such equivalent
constructions do not depart from the spirit and scope of the invention as
set forth in the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Before the present invention is described in greater detail, it should be
noted that the same reference numerals have been used to denote like
elements throughout the specification.
Referring to FIGS. 2 and 3, the first preferred embodiment of the fitting
according to the present invention is shown to comprise a mounting bracket
20, a protective canopy covering member 30 and a pair of fastening
members.
The mounting bracket 20 includes an upper major wall 201 which is adapted
to be fixed on and to abut against a flat ceiling wall, and which has two
side edge portions opposite to each other to define an uppermost abutment
plane in a radial direction relative to a first axis of an upright
coupling member (not shown), which is disposed in an upper wall of a motor
casing. Rightmost and leftmost mounting walls 202 respectively extend
downwards from the two side edge portions of the upper major wall 201.
Each of the rightmost and leftmost mounting walls 202 has a positioning
wall 24,23 which is spaced apart from the uppermost abutment plane in an
axial direction parallel to the first axis. The positioning walls 24,23
extend parallel to the uppermost abutment plane and about the first axis
so as to be angularly spaced from each other. In addition, the leftmost
mounting wall 202 further has an anchoring seat 22 which is disposed
immediately upstream of the corresponding positioning wall 23 in a
counterclockwise direction with an intervening inclining wall 221, and
which is disposed to be spaced apart from the uppermost abutment plane
with a width in the axial direction that is larger than a width between
the positioning wall 23 and the uppermost abutment plane. Moreover, each
of the rightmost and leftmost mounting walls 202 has a pair of screw holes
21 passing therethrough in the radial direction.
The mounting bracket 20 further includes a pair of arms 25 which are
disposed to be spaced apart from each other in the radial direction and
which are respectively inboard to the side edge portions of the upper
major wall 201. Each arm 25 extends downwardly from the upper major wall
201 to form an engaging half 251 which is distal to the upper major wall
201 and which extends toward the other engaging half 251 in the radial
direction to define a retaining bore functioning as a socket for receiving
the ball of a downrod (not shown).
The protective covering member 30 includes an upper annular secured portion
35 with an uppermost peripheral edge 351, and a skirt portion 36 which
circumferentially extends from the annular secured portion 35 about a
second axis and downwardly to form a lower annular wall 361 that defines
an opening 362 for insertion of the upright coupling member. In addition,
an anchored portion in the form of a hook 32 is disposed to extend from
the uppermost peripheral edge 351 of the upper annular secured portion 35
radially, inwardly and downwardly. A supported portion in the form of a
tab 33 is disposed to extend from the uppermost peripheral edge 351 of the
upper annular secured portion 35 radially and inwardly, and is spaced from
the anchored portion 32 angularly. Moreover, the upper annular secured
portion 35 further has two pairs of through holes 31 extending
therethrough in a second radial direction relative to the second axis.
Each fastening member includes a pair of screw fasteners 34 (preferably
flat-headed), each of which can pass through the respective through hole
31 and engage threadedly the respective screw hole 21.
As illustrated in FIG. 3, when the anchored portion 32 of the protective
covering member 30 is brought to engage with the anchoring seat 22 of the
leftmost mounting wall 202, the protective covering member 30 will be
suspended from the mounting bracket 20 in a non-fastened state. While
temporarily hanging in this position, the ceiling fan 10 may be
conveniently wired to the household electrical wiring.
Subsequently, the uppermost peripheral edge 351 of the protective covering
member 30 is brought towards the uppermost abutment plane from the
non-fastened state so as to bring the second axis to coincide with the
first axis. With reference to FIG. 4, a subsequent adjustment of the
position of the upper annular secured portion 35 relative to the rightmost
and leftmost mounting walls 202 in the counterclockwise direction will
shift the anchored portion 32 to the positioning wall 23 of the leftmost
mounting wall 202, thereby bringing the supported portion 33 to sit on the
positioning wall 24 of the rightmost mounting wall 202 so as to place the
protective covering member 30 in a ready state for fastening. In this
state, the user can conveniently use the screw fasteners 34 to tighten the
upper annular secured portion 35 against the rightmost and leftmost
mounting walls 202.
Referring to FIG. 5, the second preferred embodiment of the fitting
according to this invention is shown. The difference with the first
preferred embodiment resides in that the leftmost mounting wall 202 of the
mounting bracket 20 has two anchoring seats 251 similar to the anchoring
seat 22 shown in FIG. 2, two positioning walls 252 similar to the
positioning wall 23 shown in FIG. 2, and two inclining walls 253
respectively disposed between the positioning walls 252 and the anchoring
seats 251. In addition, the protective covering member 30 has two anchored
portions 32 so as to respectively engage the anchoring seats 251 in the
non-fastened state (as shown in FIG. 7) and to be shifted by guidance of
the inclining walls 253 to the positioning walls 252 in the ready state
(as shown in FIGS. 6 and 8). The screw fasteners 34 can pass through the
through holes 31 and engage threadedly the screw holes 21, as shown in
FIG. 8.
As such, before being secured on the mounting walls 202 by the screw
fasteners 34, the upper annular secured portion 35 of the protective
covering member 30 can be brought to be held thereon by the engagement
between the anchored portions 32 and the positioning walls 252 and between
the supported portion 33 and the positioning wall 24, thereby resulting in
convenience during the securing operation of the screw fasteners 34.
The present disclosure includes that contained in the appended claims, as
well as that of the foregoing description. Although this invention has
been described in its preferred form with a certain degree of
particularity, it is understood that the present disclosure of the
preferred form has been made only by way of example and that numerous
changes in the details of construction and the combination and arrangement
of parts may be resorted to without departing from the spirit and scope of
the invention.
Now that the invention has been described,
Top
